Hi. I love my Thunderbird email desktop client but at the same time I find it clunky and difficult at times. The calendar in particular could do with improvement. Please consider adding value to the way appointments and dates are presented in calendar. I would like to see the ability to colour the whole cell (specific day) when a task is entered, as opposed to just a tiny little coloured line at the side of a specific entry. For big occasions I want that date to stand out. The whole calendar needs to the ability to add more colour. Even the way the current day is "highlighted" is inadequate in my opinion. It just doesn't stand out. Also the way of setting a date range is cumbersome. Clicking and dragging the range with a mouse and extending the date range dynamically would be much easier than the current method. I'm hoping you can consider these changes. Cheers.
